vented certain new land useful Improve# #ments in -Lubricators for Slio'clGAbsorbers,

of which the following is a specification.

rThis invention relates tor shock absorbers and has special reference to a lubricator `for such shock absorbers. i

The principal object of the invention is toy provide an improved and simpliedgeneral construction of suchy shock vabsorbers yofa type adapted for general use on "automobiles andes'pecially forfconnecting the ends of the lupper and lower semi-'ellipticalsprings.I

Ay second object ofy theinvention `is [to provide an improved yconstruction of this kind wherein an improved distribution o lubricant is obtained. J

A third object of the invention isfrto provide an improved arrangement and cony struction, iny devices of this Akind having certain lubricator fparts arranged kkto act yas beariiig.pins,"the whole being vadapted to be readily assembledin connection with la shock absorber.

With the above and other objectsin view, y

as will be hereinafter apparent, the invention consists in general of certain novel details of construction and. combinations yof parts hereinafter fully described, illustrated in the accompanying "drawings and speciically claimed. i v y a 'e vIn the accompanying drawings, like characters of reference indicate like parts inthe several views, andFigure 1 is a vertical"` transverse median section through a shock absorber provided with ra lubricator `arrangement forming this invention; Fig. 2

is a section on the line 2 2 of Fig. 1.; Fig.V

3 is a side view of such a shock absorber and lubricator; Fig. 4 is an yend view partly broken away. i f. i

In carrying out `the objects of this invenvtion there is provided ka pair of ymembers .10 which are preferably drop-forgings and which each haver aborell and a bolt stem 12 threaded at its A'outer endy as indicated at 13. Eachk bolt stem extends from `the body adjacent 'one endy thereof, as clearly shown in Fig. 1.

`At 14 isa bottom member, preferably drop forged and provided centrally with a M. MALoNnY,

cup-shaped spring seat 15 having itsbottoiii open asy at 16.y Extendingjfrom this spring" seat are diametrically-disposed "lugs 17 having threaded apertures for the reception of thethreaded ends 13 of the 'members 10.'

.y Speceation'of Letters Patent. atnted Jan, 18,1916,

By means of this construction theV bottom member 1&1 constitutes ayolreto kcarry the members 10. However, prior to assembling the bottom'i/iiember 14, and the members 10,

the bolt stenis12 arefpassed through suitable ears formed on anfup'per'rspring seaty member 19, such member having mits bottom aspring receivingjcupy20, the bot- `toin of the cup being upward and having a' Y, e,

centrally disposed opening, as clearly shown in Fig". 1. The 'ears 18 are each kprovided v with an upper bushing 21 and a lower bush.

ingf22 spacedfroin they uppeif bushiiig to provide a' chan'iber -23 lsurrounding the re-y spective stem 12 for tliepassage or reception 'of oil or other ysuitable lubricant."

Leading "tov one of these chambers is passage ?Qiwhich communicates 'with the in# terior of thekbody 25 ofa grease cup,'this bodyl being preferably formed integral with the lug l18 and having screwed. thereonwajcap Y 26 so"r that a compression grease cup is# Y formed. Alinedfopposite the opening'24is a.

pinreceiving opening or bearing 27 which alsorcommunicates with theV chamber 23 on that side.

' On the opposed side ofthe member y19 is provided a lateral passage alined with the Vopenings 24 .and 27, and the inner end 28 of which forms a pin-receiving opening while the outer end 29 is threaded to receive a threaded plugV 30, this outer end beingy slightly largergthan the inner end so that a pin 31 may be passed therethrough into the bearings, this being, of course, donebefore the member 19 is placed on the stems 12.y This pin has an axial opening 32 extending therethrough so that communication is afforded between :the two chambers 23 thus` permitting grease to pass from the cup through the right-hand chamber 23 and into 'the left-hand chamber 23 whereby lubrication of both stems 12 iseffected. Leading from the opening 32 is a lateral opening 33 which communicates with a groove 34 on the surface of the pin soythat grease ymay be Y forced therein 'for the purpose of lubricat-r4 ing the eye 35 of the spring member 36.

Through'the openings 11 is a spring-bean L f ing pin 37 having an enlarged hollow head` Y eye 44 of' theV springl maybe lubricated.
